EXTENSION GUARD-RAIL.

SPECIFICATION forming part of Letters Patent No. 565,338, dated August 4, 1896. Application filed January 13 1896. Serial No, 575,337. (No model) To a whom it may concern.-

Be it known that I, JUAN WV. ERNEST, a citizen of the United States, and a resident of Los Angeles, in the county of Los An geles and State of California, have invented certain new and useful Improvements in Extension Guard-Rails, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

The object of this invention is to provide an extension guard-railfor election-booths, rooms, and other compartments which can be quickly extended to fit varying sizes of rooms, a further object being to provide a guard-rail the supports of which can be arranged to suit any room and quickly and firmly attached at any point to the rail, and as quickly folded in a small space for handling and storing; and with these and other objects in View the invention consists in the novel construction, combination, and arrangement of parts here inafter described and claimed.

I11 the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of my improved guard-rail, showing three compound-lever supports gripping the rail and supporting the same; Fig. 2, a View of the rail with the separable parts thereof disconnected; Fig. 3, a side View of one of the gripping-supports; Fig. 4, a similar View showing a modified form of the support, and Figs. 5, 6, and 7 represent details of the construction. 7

The guard-rail is composed of separate sections A and B, and secured to one of said sections is a loop 0, through which one end of the other rail is adapted to be passed, and the other end is provided with a suitable device for fastening it at various points to the companion rail. .The device shown is the pin or bolt E, which projects at right angles therefrom, and which is provided with a head E and the opposite end of said bolt is threaded and provided with athumb-nut for operating said bolt, (shown in dotted lines in Fig. 2,) and in ,the companion rail are formed longitudinal apertures D, at one end of which is a circular opening 01. By means of this construction it will be seen that the section A, provided with the apertures D, and the secand in Fig. 1 three are shown.

tion B may be longitudinally adjusted by simply passing the head of the bolt E through the circular openings cl and then adjusting said sections until the bolt enters the adjacent narrow opening, and then by tightening the thumb-nut the two sections will become as one piece and of the length determined by the position of the bolt.

Instead of the bolt and long openings above described a variety of devices can be substituted, one of which is shown in Fig. 7 and consists of a bolt E, provided with a woodscrew thread at one end, and the other end being flattened and provided with a head like a thumb-nut, and a space between left smooth,

to which is attached the plate J, provided with screw-holes through which it may be fastened to the rail, so that the bolt will be in the same position as the one above described,

and instead of the apertures described a number of holes can be made in the companion rail which will be smaller than the bolt, so

that the thread on the bolt will catch and hold-therein, and the operation will be readily understood and is practically the same as that above described.

The supports for the adjustable guard-rails consist of separate legs G and G which are pivotally connected near their upper ends by two cross-pieces g and near their lower ends by sectional cross-bars g which are pivotally connected at their adjacent ends, as shown at g, and formed in the top of one section thereof is a notch or recess g which is adapted to receive a lug or projection g, which is formed upon or secured to the other section. A rivet or screw or is passed through the leg G and the piece 9 to steady the operation of the de- 0 v1ce.

The adjacent upper ends of the legs G and G are cut out so as to form angular notches or openings with parallel sides, and secured therein are metal plates H, which are pro- 5 vided with teeth or projections on their inner surfaces, and between which the guard rails are adapted to be gripped. Any desired number of these supports may be provided,

In the construction shown in Fig. 3 the adjacent sides of legs G and G are provided with a vertical groove h, in which the sectional cross bars or braces 9 are pivoted, and

to fasten these supports to the floor, and I provide for this purpose a long wood-screw at the bottom of each leg, which is entered in an aperture at '21, said aperture extending down about half the length of the screw, and large enough that the head of the screw may be easily operated by an ordinary screwdriver. The screw with its point even with the bottom of the leg and the head and the upper half in the aperture is out of the way in ordinary use, but, if wanted, it can be,

screwed down into the floor until its head bears on the bottom of the aperture, thus providing a cheap, strong, and convenient fastening.

, Pivot-ally connected with the free or outer end of the section A of the adjustable guardrail is an arm K, which is adapted to serve as a gate and to close the space between the guard-rail and the side of the booth,room, or

compartment, (not shown,) and inserted in the guard-rail, adjacent to the pivotal connection of said arm, is a pin 7.1,. against which the end of the arm is adapted to abut, and by means of which the latter may be held in a horizontal position, as shown in Fig. 2, and

if an exit-gate is desired a similar device may j legs which are pivotally connected near their also be attached to section B of the guard rail.

On reference to the dotted lines in Figs. 3 and 4. it will be readily seen that the braces g when pressed. downward will exert a great leverage on the legs G, and the length of the legs to the fulcrum g constituteanother powerful lever, and there is, therefore, a 00111 pound lever of great power to grip the rail,- which, by the aid of the teeth or projections of the plates H, take a firm hold of the rail and become as a piece and part of it.

My invention is not limited to the exact form, construction, and arrangement-of the various parts, and I therefore reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

Having described my invention, I claim as new and desire to secure by Letters Patent 1. An adjustable guard-rail, consisting of separate sections one of which is provided with a loop through which the other is adapted to be passed, one of said sections being also provided with longitudinal apertures through which a pin or bolt connected with the other, is adapted to pass, substantially as shown and described.

2. The herein-described adjustable guardrail, consisting of separate sections, one of which is provided with a loop through which the other is adapted to be passed, one of said sections being also provided with longitudinal apertures through which a pin or threaded bolt connected with the other, is adapted to be passed, and said apertures being provided at one end with a circular openin g which is adapted to receive a head formed on said pin or threaded bolt, substantially as shown and described.

3. An adjustable guard-rail, consisting of separate sections one of which is provided with a loop through which the other is adapted to be passed, and one of said sections containing apertures through which a pin or threaded bolt connected with the other, is adapted to be passed, and one of said sections having a swinging arm connected with the I end thereof and provided with means for hold" in g it in a horizontal position, I p

4. An adjustable guardrail, consisting of separate sections, one of which is provided with a loop at one end and a swinging arm at the other end, the other section adapted to pass through the aforesaid loop, and provided at one end with suitable means for se* "curing it temporarily at the intermediate points between the loop and the swinging arm of the other section. I

5.

A support for a guard-rail, consistingof upper ends by a rod or bars, said upper ends being also provided with angular apertures 3 in their adjacent surfaces, in which are placed or secured plates provided with teeth or projections and the lower ends of said legs being connected by sectional bars or braces,

one of which is pivotally connected with each leg, and said bars or braces, being alsoipivotally connected, substantially as and for the purpose set forth.

7. A support for a guard-rail, consisting of legs which are pivotally connected near their upper ends by a rod or bars said upper ends being also provided with angular apertures in their adjacent surfaces, in which are placed or secured plates provided with teeth or projections and the lower ends of said legs be ing connected by sectional bars or braces,

; one of which is pivotally connected with each leg, and said bars or braces being also pivotally connected, and said legs being provided a with vertical grooves in which said sectional bars or braces are pivoted, substantially as Y and for the purposes set forth.

8. A suitable support for a guard-rail, provided atthe lower ends of its legs with an ordinary wood-screw, the head and upper half of said screw working in an aperture in the leg adapted to permit the operation of said screw, substantially as and for the purposes set forth.
